Deutsche Bahn is transitioning to amber-colored 1800 K LEDs at train stations to reduce light pollution and insect stress.

New Lighting at Train Stations Reduces Light Stress for Insects https://leibniz-lib.de/en/news/11092026-new-lighting-at-train-stations-reduces-light-stress-for-insects.html Paper by Carmen Ludreschl et al.: https://www.sciencedirect.com/science/article/pii/S0006320726002764 "The amber-coloured 1800 K LED attracted significantly fewer #insects than the current standard (cool white 4000 K LED) and the old high-pressure sodium lamps (2000 K)... #DeutscheBahn has already responded to the findings: all the platforms studied, as well as one additional station, have been permanently converted to the new LEDs."
